Efficacy and Safety of Org 25969 Administered After Zemuron® (MK-8616-042)

August 30, 2018 updated by: Merck Sharp & Dohme LLC

A Multi-center, Randomized, Assessor-blinded, Phase II, Parallel Dose-finding Trial in Subjects of ASA Class 1 - 3 to Assess the Efficacy and Safety of 5 Doses of Org 25969 When Administered at 1-2 PTCs After Administration of Zemuron®

The primary objective of this study is to explore the dose-response relation of MK-8616 (Org 25969) given as a reversal agent of Zemuron® at 1 to 2 post tetanic counts (PTCs); both Zemuron® and MK-8616 are administered by intravenous (iv) infusion. Another goal of the study is to evaluate the safety of single doses of MK-8616 administered to participants of American Society of Anesthesiologists (ASA) Physical Status Class 1 (otherwise normal, healthy participant); Class 2 (participant with a mild systemic disease); or Class 3 (participant with a severe systemic disease that limits activity, but is not incapacitating).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time From Start of Administration of MK-8616 to Recovery T4/T1 Ratio to 0.9
Time Frame: Up to 90 minutes
The mean time from the start of MK-8616 administration to recovery T4/T1 ratio of 0.9 was determined. Less time indicates faster recovery from NMB. The ratio of T4 (fourth twitch; amplitude of fourth response to train of four [TOF] stimulation is expressed as percent of control T4) over T1 (first twitch; amplitude of first response to TOF stimulation is expressed as percent of control T1) ranges from 0 (complete loss of T4 twitch response) to 1.0 (complete recovery of T4 twitch response). For TOF stimulation, 4 consecutive square wave supra-maximal stimuli of 0.2 msec duration were delivered at 2 Hz every 15 seconds. Neuromuscular monitoring was performed with the TOF-Watch® SX.
Up to 90 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Experiencing ≥1 Adverse Events (AEs)
Time Frame: Up to 7 days following MK-8616 administration
The percentage of participants experiencing ≥1 AEs was determined. An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment.
Up to 7 days following MK-8616 administration
